My understanding of chloramine is that it is very difficult if not
impossible to remove just by aeration. (That's one of the reasons they use
it) However, not all water treatment authorities use chloramine and perhaps
you should check with Sydney Water to see if they actually use Chloramine. I
know they do in Brisbane and were the first water authority to do so. When
they first started using it there was massive fish kills in aquariums that
only treated their water with chlorine removers. Even one of Aquasonics
"Chloramine" remover did not remove the chloramine in Brisbane water and
they (Aquasonics) had to make a higher strength product (Chlormon - it used
to be called Extra Strength) to treat Brisbane water which works very well
now. Other manufacturers have followed suit. Having said that I would not be
surprised what they may be dumping in it now! ( Probably creating disastrous
results for kidney dialyses patients?)
